Key Questions Answered
What is the current status of TSLint and ESLint in 2019?
As of 2019, TSLint is the standard linter for TypeScript, while ESLint serves the JavaScript community. TSLint has a core rule set and community-maintained packages, but ESLint offers features like conditional lint configuration and automatic indentation that TSLint lacks.
Why is Palantir deprecating TSLint in favor of ESLint?
Palantir is deprecating TSLint to unify the linting experience for TypeScript and JavaScript developers. This decision aims to reduce barriers for JavaScript developers transitioning to TypeScript and to leverage ESLint's more efficient analysis infrastructure.
What steps will Palantir take to support TSLint users during the transition?
Palantir plans to provide a smooth transition to ESLint by contributing features and plugins, including support for writing ESLint rules in TypeScript and testing infrastructure improvements. They will also ensure continued compatibility of TSLint with new compiler versions until the transition is complete.

Key Actionable Insights
1Developers should start migrating their TypeScript projects from TSLint to ESLint to take advantage of improved features and community support.This migration will not only enhance the linting experience but also align TypeScript development with the broader JavaScript ecosystem, making it easier for developers to adopt TypeScript.
2Utilizing ESLint's TypeScript support can significantly reduce the complexity of managing linting rules across JavaScript and TypeScript projects.By leveraging ESLint, developers can maintain a consistent linting strategy, which is crucial for team collaboration and code quality.
Common Pitfalls
1
One common pitfall is the reluctance to transition from TSLint to ESLint due to the perceived complexity of migration.
This reluctance can lead to fragmentation in the development process and hinder the adoption of TypeScript features. Developers should recognize that transitioning to ESLint can streamline their workflow and enhance their code quality.
